Month: 2025-10 — This period delivered security, observability, and reliability improvements across cloud-gov/deploy-cf and cloud-gov/terraform-provision. Key features and fixes include upgrading the User Authentication System to UAA 77.20.8 to apply release fixes, and delivering enhanced monitoring infrastructure for Workshop and Pages environments with DNS provisioning, Terraform-based infrastructure configurations, and pipeline adjustments to enable Prometheus, AlertManager, and Grafana. A subnet allocation fix was implemented to prevent IP conflicts in the monitoring stack. These efforts reduce risk, improve incident response, and provide scalable observability for production and workshop environments.
